# wikt-page-text-command

The groupant beside tools/wikt-page/src/main.rs in the Mova repository: what the code computes, what it never does, how to go back from its outputs, its invariants, cost and checks.

## Model text


### descriptant

#### wikt-page-text-command

##### Epoch 2026-10-31

Full source read preceded changes. Prospective model predicted branch/order, resource and information-loss behavior. Tests exercise actual helpers on bounded synthetic inputs; command workflows remain unexecuted. Production source prefix is preserved; only inline tests added.

Sorted index files scanned until all unique requested titles found; matching index record yields paired XML file and offset. For each original requested title decode one bz2 stream, parse exact title's first text, print ids/body; missing titles count and exit1 after other outputs.

Executable percentage approximation is unsupported: categorical parsing/effects have no useful certified metric here. Partial syntax excludes macro expansion and name resolution.

### approximant

#### Forward relation

Sorted index files scanned until all unique requested titles found; matching index record yields paired XML file and offset. For each original requested title decode one bz2 stream, parse exact title's first text, print ids/body; missing titles count and exit1 after other outputs.

##### Domain

Paired index naming conventions, valid seek offsets/bzip2 streams and UTF-8 XML text; quick_xml end-name check disabled. Filesystem/index scanning and compressed helper execution remain gaps in current pure checks.

### composition

#### Local composition

The scoped xml-page fragment models its declared source interval. Parent relation: Sorted index files scanned until all unique requested titles found; matching index record yields paired XML file and offset. For each original requested title decode one bz2 stream, parse exact title's first text, print ids/body; missing titles count and exit1 after other outputs.

Shared representation/invariant: Index title keys deduplicate search, but original request duplicates repeat decode/output. read_stream single BzDecoder stops at stream end. find_page first page/revision id avoids contributor id and returns at text before full page validation. Child costs are included in parent costs, not added a second time. Other command paths are tagged alternatives; the child alone does not establish whole-file behavior.

### models

## Typed source models

All models are partial source-derived relations at this manifest snapshot. Scope is one call/trace under the stated domain; no universal semantic proof.

### behavior_complement

Exact title mismatch cannot return page text; missing paired XML fails before opening index stream; unknown entity errors at unescape.

Domain: Paired index naming conventions, valid seek offsets/bzip2 streams and UTF-8 XML text; quick_xml end-name check disabled. Filesystem/index scanning and compressed helper execution remain gaps in current pure checks. Observation: Index title keys deduplicate search, but original request duplicates repeat decode/output. read_stream single BzDecoder stops at stream end. find_page first page/revision id avoids contributor id and returns at text before full page validation. Assumptions: bounded resources and source branch semantics. Oracle: selected actual-helper tests in tests.md constrain only their finite fixtures; remaining branches are source-derived.

### reverse_reconstruction

Page projection admits XML with arbitrary contributor metadata/unused fields; index lookup offset+file admits many index page ids because that field is ignored.

Domain: Paired index naming conventions, valid seek offsets/bzip2 streams and UTF-8 XML text; quick_xml end-name check disabled. Filesystem/index scanning and compressed helper execution remain gaps in current pure checks. Observation: Index title keys deduplicate search, but original request duplicates repeat decode/output. read_stream single BzDecoder stops at stream end. find_page first page/revision id avoids contributor id and returns at text before full page validation. Assumptions: bounded resources and source branch semantics. Oracle: selected actual-helper tests in tests.md constrain only their finite fixtures; remaining branches are source-derived.

### index_filename_transport

Replace first -multistream-index and first .txt only, retain partition suffix; exists guard is not file-type validation.

Domain: Paired index naming conventions, valid seek offsets/bzip2 streams and UTF-8 XML text; quick_xml end-name check disabled. Filesystem/index scanning and compressed helper execution remain gaps in current pure checks. Observation: Index title keys deduplicate search, but original request duplicates repeat decode/output. read_stream single BzDecoder stops at stream end. find_page first page/revision id avoids contributor id and returns at text before full page validation. Assumptions: bounded resources and source branch semantics. Oracle: selected actual-helper tests in tests.md constrain only their finite fixtures; remaining branches are source-derived.

### stream_extent

Seek absolute u64 then single BzDecoder read_to_string; no Multi decoder and no neighboring stream aggregation.

Domain: Paired index naming conventions, valid seek offsets/bzip2 streams and UTF-8 XML text; quick_xml end-name check disabled. Filesystem/index scanning and compressed helper execution remain gaps in current pure checks. Observation: Index title keys deduplicate search, but original request duplicates repeat decode/output. read_stream single BzDecoder stops at stream end. find_page first page/revision id avoids contributor id and returns at text before full page validation. Assumptions: bounded resources and source branch semantics. Oracle: selected actual-helper tests in tests.md constrain only their finite fixtures; remaining branches are source-derived.

### identifier_precedence

First id before revision fills page.id, first id after revision fills rev; subsequent contributor ids ignored. page start resets all fields.

Domain: Paired index naming conventions, valid seek offsets/bzip2 streams and UTF-8 XML text; quick_xml end-name check disabled. Filesystem/index scanning and compressed helper execution remain gaps in current pure checks. Observation: Index title keys deduplicate search, but original request duplicates repeat decode/output. read_stream single BzDecoder stops at stream end. find_page first page/revision id avoids contributor id and returns at text before full page validation. Assumptions: bounded resources and source branch semantics. Oracle: selected actual-helper tests in tests.md constrain only their finite fixtures; remaining branches are source-derived.

### partial_output_failure

Requested titles printed sequentially; later decode/XML failure leaves earlier stdout. Missing title reports continue then exit1; no rollback.

Domain: Paired index naming conventions, valid seek offsets/bzip2 streams and UTF-8 XML text; quick_xml end-name check disabled. Filesystem/index scanning and compressed helper execution remain gaps in current pure checks. Observation: Index title keys deduplicate search, but original request duplicates repeat decode/output. read_stream single BzDecoder stops at stream end. find_page first page/revision id avoids contributor id and returns at text before full page validation. Assumptions: bounded resources and source branch semantics. Oracle: selected actual-helper tests in tests.md constrain only their finite fixtures; remaining branches are source-derived.


### tests

#### Native evidence — 2026-10-31

Package/bin: `wikt-page`. Exact selected names:

- `wave33::xml_ids_text_and_empty_page`

All 1 selected checks passed twice in debug and twice in release, one exact name per invocation with one test thread. Numeric exits are zero; sorted named outcomes match across all four runs. Added test blocks were formatted before these receipts; original source prefix (including earlier tests) remains byte-identical.

One compiled production mutant changed `first revision id capture` to `disable revision id capture`. The new wave33 test compiled and failed its runtime assertion (exit 101). Exact original/restored SHA-256 equality and a restored positive exact test (exit 0) were verified. No assertion-only mutant is counted; existing negative assertions remain ordinary tests. No surviving compiled mutant is omitted.

The external wave33 text receipts retain native-commands.json, verified-outcomes.json, mutation-report.json, raw logs/statuses, paired syntax projections and prospective.md. No private filesystem path is part of this public model.

Scope: actual helpers on synthetic in-memory data only. Paired index naming conventions, valid seek offsets/bzip2 streams and UTF-8 XML text; quick_xml end-name check disabled. Filesystem/index scanning and compressed helper execution remain gaps in current pure checks. The scoped fragment reuses these tests where its helper is reached; other declared paths remain source-derived. Macro expansion, full command/effect execution, corpus accuracy and universal correctness are not established.

### invariant-and-cost

#### Invariant and cost

##### Invariant

Index title keys deduplicate search, but original request duplicates repeat decode/output. read_stream single BzDecoder stops at stream end. find_page first page/revision id avoids contributor id and returns at text before full page validation.

##### Cost

O(index bytes until found + sum decoded stream sizes per requested occurrence); repeated same stream not cached. Memory index line plus full decoded stream and output text.

Arithmetic and allocation premises are conditional. No timing or percentage surrogate claimed.
